Omega-6 and omega-3 fatty acid nutrition amongst Malaysians are far from desirable

Abstract

This paper reviews available reports on the omega-6 (linoleic acid, LA) and omega-3 fatty acid [alpha-linolenic acid (ALA) + eicosapentaenoic acid (EPA) + docosahexaenoic acid) intakes amongst Malaysians against Malaysian Recommended Nutrient Intakes (RNI), focussing particularly on pregnant and lactating women because of the availability of data for these latter vulnerable groups. Overall, the omega-6 and omega-3 fatty acid nutrition amongst Malaysians are poor and far from desirable. The nutritional situation regarding these long-chain polyunsaturated fatty acids (LCPUFA) amongst Malaysian pregnant and lactating women is alarming and warrants urgent attention in nutrition promotion activities/counselling. Daily consumption of LA by these women and other Malaysians studied ranged from 3.69-5.61 % kcal with 38-60% of individuals not meeting their RNIs. Daily intakes of omega-3 fatty acids faired worse, averaging 0.21-0.33 % kcal with as high as 92% of subjects in one study not meeting their RNIs. The omega-6 to omega-3 fatty acid ratios obtained in the studies reviewed are about 20:1, which is way above the World Health Organisation-recommended ratio of 5-10:1. Dietary sources of these omega-fatty acids in the subjects studied are chicken, fish and milk. Since local foods are not particularly rich in LCPUFA such as EPA and DHA, the options to improve EPA/DHA nutrition amongst Malaysians are the greater consumption of omega-3 enriched foods and in the case of pregnant and lactating women, LCPUFA supplementation may warrant serious consideration.
